STONE-CLEANING COMPOSITION ANO METHOD OF MAKING SAME.

SPECIFICATION forming part of Letters Patent No. 754,417, dated March15, 1904.

Application filed June 9, 1902. Serial No- 110,772. (No specimens.)

To all whom it may concern:

Be it known that I, Pmzur J. BRAHEN, a citizen of the United States,residing in Hart ford, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inStone-Cleaning Compositions and Methods of Compounding the Same, ofwhich the following is a specification.

This invention relates to renovating stone, and has for its objects toprovide an improved stone-cleaning composition and a method forcompounding the same.

As is well known, stone and marble structures which are exposed to theelements become soiled and stained and in certain instances becomecovered with moss and mold, all of which it is diflicult to remove,whereby to restore the original beauty of the material of the structure.I provide, therefore, an improved renovator by which it is possible toremove mold, moss, stains, dirt, &c., leaving the stone in a conditionsimilar to that in which it'was when it was first tooled, and thiswithout great expense, time, or labor and without any disagreeable odor.The stone after being subjected to treatment by the improved renovatorwill remain in its natural beauty for as long a time or longer as thenew stone remained.

The improved renovator is composed of or results from the mixing of thefollowing ingredients: chlorid of lime, (calcium hypochlorite,)"(Eal6iiimfcarbonate;)ffsj6; ki fsfin i ijeitliiidfiilim bonajegzrt Theingredients may be prepared for use and compounded in the foll wingproportions:

First mix one and one-h pounds or twelve parts of chlorid of lime(calcium hypochlorite) and one-half pound or four parts of whiting(calcium carbonate) together in some convenient vessel. Then dissolvetwo ouhces or one part of sodium chlorid and two pounds or sixteen partsof sodium carbonate in four quarts or sixty-six and two-thirds parts ofboiling water and pour over the mixture of chlorid of lime and whitingand stir slowly until thoroughly mixed. The mixture may be permitted tostand from four to six hours before using.

In using the renovator it may be applied to the stone or marble in anymanner-as, for instance, with a spray or brush. After it has remainedupon the surface for a few min utes it may be rubbed with a scrubbing orother brush, when the original beauty of the stone will be restored.

Having thus described my invention, I claim 1. The method of compoundinga cleaning composition for stone and marble which consists in mixingtogether twelve parts of chlorid of lime, and four parts of whiting,then dissolving one part of sodium chlorid and sixteen parts of sodiumcarbonate in about sixtysix and two-thirds parts of boiling water, thenpouring the same over the chlorid of lime and whiting and slowlystirring the same.

2. The method of compounding a cleaning composition which consists inmixing together chlorid of lime and whiting in about the proportionsstated, then dissolving sodium chlorid and sodium and sodium carbonatein water, in about the proportions stated, then introducing the same tothe mixed chlorid of' lime and whiting.

3. A cleaning composition resulting from the mixing of twelve parts ofchlorid of lime, four parts of whiting, sixteen parts of sodiumcarbonate, one part of sodium chlorid and sixty-six and two-thirds partsof water.
